B57620C103J62 – EPCOS

The B57620C103J62 is a negative temperature coefficient (NTC) thermistor manufactured by EPCOS. This discrete thermistor exhibits a nominal resistance of 10 kΩ at 25°C (R25). Its primary function is temperature sensing and compensation within electronic circuits. The “J” suffix in the part number denotes a resistance tolerance of ±5% at the specified R25 value. This component’s resistance decreases non-linearly with increasing temperature, following a characteristic curve defined by its material composition and geometry. The B57620C103J62 is typically utilized in applications requiring precise temperature measurement or control, such as temperature monitoring in power supplies, battery chargers, and automotive electronics, where accurate and reliable temperature-dependent resistance is crucial for circuit operation and protection.
